.APPARATUS FOR ASGERTAINING THE CHARATERTSTICS OFFLOW-ING LIQUIDS.

Application med Jury 5, 192s, serial No. 849,537.' Renewed my a, is28.

This invention relatesy to improvements in an apparatus forascertaining the4 characteristics of flowing liquids, and refers more particularly to a meansl for.-checking the gravity and temperature 'of hydrocarbon oils asthey are withdrawn from-the system.

Among the objects of theinvention are to provide an apparatus whereby llqulds such as oils are vintroduced to communicating containers, the oil being suppliedto one container and maintained in a relatively stagnant `pool in a communicating chamber whereby gauging instruments such Vas hydrometers, thermometers or the like, may be positioned 1n the stagnant pool and accurate readings tale en, the liquid passing continuously through 'l the pipes and being maintained at a constant liquid level by .suitable apparatus; to provide an apparatus whereby agitation of the oil in the containers is reduced by permitting any gas contained in the liquid .to be separated therefrom prior to its introduction into the containers,and in general'to provide an apparatus of thecharacter referred to.

' Fig, 1 is a side elevationalview of the apparatus with parts in section.

Fig. 2 is a view showingthe method by means of which the liquid level is controlled.

Referring to the drawings, the apparatus consists of an outer container l in which is positioned an inner container 2 having a plurality of holes ,3 inthe periphery of the inner container, whereby any liquid introduced to the outer container by means of the pipe 4 will assume a common level in the two con- 'tainers due to the communicating ports 3.

The liquid is introduced through the pipe 4 from afnyconvenient source, not shown, and

' has a free vertical fall Iinto the Outer container so that any gas contained inthe liquid may separate therefrom, thus eliminating agitation which would normally result with the introduction of the liquid containing gas, were the liquid introduced below the liquid levels in the containers. This elimination of bub- I bling due to gas contained in the liquid, also does away with any foam which may collect as a result of gaseous material in the liquid.

Near' the bottom of the outer container is a draw-Cif line 5 which has connected therewithI an inverted Ul` tube 6 which terminates as a discharge line into a lower funnel 7.

When in a vertical position, the'upper portion of the U tube is somewhat above the top of the containers, but is adjustable from a vertical position at any inclination desirable, soy that the liquid level in the two containers may be fixed at any desired height byhrotating the inverted U -tube to any desired inclination and the two containers.

This double flask arrangement permits the i l maintenance-of a relatively stagnant pool of Oil in the inner container, which has a smooth gravity readings may be made, although the liquid is continuously passing through the pipes. The elimination of bubbles caused by gas in the liquid, is ani'important-feature Of the invention. i

The liquid overowin'g through the U tube `into the funnel '7 may berconductd to any suitablev storage, not shown.

As stated, this device may be used in con nection w1th' any apparatus for treating liq- .uids where it is of importance to ascertain continuously throughout the operation of the process, information concerning the characteristics ofthe liquid produced.

A furtherpurpose and advantage of thel invention is the positioning of an Outlet or drawoif ofv the flowing liquid at the bot-tom of the cylinderor container to` remove continuously all fractions of various gravities of the, liquid and thereby obtain4 an accurate measure of the characteristics of the liquid.-

The accumulation of theheavy fractions at the bottom of the apparatus would give 1ncorrect measures or incorrect determinations of the Characteristics of the liquid being tested nearthe upper portion, thus by continually drawing off the different types .of

'case of emergency, inremoving liquidfrom .liquid level by lmeans of which accurate i distillate as they come over, an accurate determination of the characteristics of each liquid may be obtained. We claim as our invention:

1. In anapparatus for testing owing liquids, the combination with open communi- 'cating containers of substantially uniform height,ijof means for introducing a. liquid to one of said containers whereby a relatively stagnant testing pool of liquid is maintained in the communicating container, an overflow from the lirst mentioned container for maintaining a liquid level in ,the two containers.

2, ln an apparatus for testing fiowing liqnids,A the combination with communicating liquid-containers, one positioned inside of thc other, and having a common liquid level, of means, positioned above the liquid level for .v introducing liquid' to the outer container,

whereby a relatively stagnant pool` is maintained in the inner' container, a liquid level controllingT means connected with the outer of the other and having a common liquid" level, of means positioned above theA liquid level for introducing liquid to the outer container whereby a relatively stagnant pool is maintained in the innerv container, a liquid level controlling meansvconnecting with said containers, and independent means for withdrawing liquid from each of said containers.
